Perhaps your inquiry could benefit from a rephrasing that would maybe include the word in question.

Welcome to Productivity.SE! Please make more effort before and during you write your question. We don't have a single clue what exactly you are talking about. We can't give a definitive answer this way, it's best that you just stop drinking it for yourself and look whether better sleeping habits develop over the next days.

Note that working at the computer up till before you go to sleep is more likely to be a cause for excitement. You may wanna check out F.lux if that's your case.

Teas that does not contain caffeine, as herbal teas, have relaxing effect and a cup of tea before bed may help sleeping. Chamomile is the most famous but others too have similar effect.

Teas that contain caffeine have the same effect as coffee with respect to sleep. However, tea has more health benefits than harm while coffee is more harmful than useful.

Each type of coffee or tea contains different amounts of caffeine. Each individual reacts differently to caffeine. Also each individual has different threshold. By experience, one can tell what works better.

If a person needs something to help staying awake, tea is a better choice than coffee. However, before drinking a lot of it a personal physician must be consulted.

Herbal tea isn't really tea, it's an infusion which doesn't include the tea plant (Camellia sinensis). Also, do you have any evidence that coffee is more harmful than useful?

That's an article about caffeine, not coffee. If you'd have said caffeine is more harmful than useful then I wouldn't have mentioned it. Also, the caffeine in tea is exactly the same as the caffeine in coffee, there's just less of it on average.

Tea contains theïne which is the same caffeine but for some reason they like to call it theïne. The amount of caffeine differs per tea.

Chamomile and green tea are not for there relaxing effect.

There is also tea that contains no caffeine (theine) in Dutch it is called "Rooibos" i'm unable to find the English naming. Rooibos tea is prepared from any of several species of Borbonia or Aspalanthus, believed to have tonic properties
